Without a well-focused question, it could be difficult and time-consuming to identify appropriate resources and search for relevant evidence. Practitioners of Evidence-Based Practice (EBP) use a specialized model framework, called PICO, to form the question and facilitate the literature search1.
P | Patient, Population, or Problem | How would I describe a group of patients similar to mine? |
I | Intervention, Prognostic Factor, or Exposure | Which main intervention, prognostic factor, or exposure am I considering? |
C | Comparison or Intervention (if appropriate) | What is the main alternative to compare with the intervention? |
O | Outcome you would like to measure or achieve | What can I hope to accomplish, measure, improve, or affect? |
What Type of question are you asking? | Diagnosis, Etiology/Harm, Therapy, Prognosis, Prevention | |
Type of Study you want to find | What would be the best study design/methodology? |
